This commits adds a gpu node in mt8370.dtsi to enable support for the ARM Mali G57 MC2 GPU (Valhall-JM) found on the MT8370 SoC, using the Panfrost driver. On a Mediatek Genio 510 EVK board, the panfrost driver probed with the following message: ``` panfrost 13000000.gpu: clock rate = 390000000 panfrost 13000000.gpu: mali-g57 id 0x9093 major 0x0 minor 0x0 status 0x0 panfrost 13000000.gpu: features: 00000000,000019f7, issues: 00000003, 80000400 panfrost 13000000.gpu: Features: L2:0x08130206 Shader:0x00000000 Tiler:0x00000809 Mem:0x1 MMU:0x00002830 AS:0xff JS:0x7 panfrost 13000000.gpu: shader_present=0x5 l2_present=0x1 [drm] Initialized panfrost 1.3.0 for 13000000.gpu on minor 0 ``` Signed-off-by: Louis-Alexis Eyraud <louisalexis.eyraud@collabora.com> --- arch/arm64/boot/dts/mediatek/mt8370.dtsi | 9 +++++++++ 1 file changed, 9 insertions(+)
